Very good extension. However I noticed with some of the styles I'm not able to see some high resolution pics and sometimes they are barely visible, added to that the missing or barely visible content, so basically the only way to rectify this is to constantly switch between different styles depending on the site you are on which is very tedious and annoying, the styles need to be uniform across all webpages. Btw...If you can create #21 to have the same grey on black fonts as #8 that would be perfect.
